Application filed July 17, 191

To all whom it may concern.-

Be it known that we, Louis J. RnroHnL and l/VILLIAM L. WARNER, citizens of the United States, and residents of Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Looking Means for Printers Forms, of which the following is a description, reference being had to the accompanying drawing, which forms a part of our specification. I

Our invention relates to means whereby printers forms may be firmly locked within the chase so that the various parts assembled in the frame or chase will be held against any shifting or accidental loosening.

Our invention has for its object the provision of means which will provide an absolute lock for the forms in the chase, whereby the necessity of employing wads of paper, card-board, or plugs of lead, as is the usual practice today in order to secure the necessary fine adjustment of the form, is eliminated; and in addition to the considerable saving of time accomplished also obviates the necessity for employing a great number of wedging elements or slugs.

The invention further contemplates means which will permit adjustment of the forms on what may be termed the point system, whereby the operator is assisted in adjusting or moving his forms in the chase to se cure a perfect register, especially where multi-colored printing is to be done; the improved means enabling the quick adjustment or tipping of a cut for register; while at the same time providing a proper bean ing or firm hold on all sides of the cut; the means being such as to permit the adjustment to any angularity within reasonable limits and yet provide a firm and square contact with the furniture and the forms or cuts.

Our invention is especially adapted for use in connection with large forms, wherein it greatly facilitates any individual adjustment or movement desired of a single cut or portion of the form without in any way disturbing the permanent lock-up; the con struction being such that it till withstand the vibration to which it is subjected during the operation of the press.

The invention and its advantages will be more readily comprehended from the follow- Specification of Letters Patent.

Fig. 4 is a side elevation of tlie two quoin sections, shown in Figs. 2 and 3, placed in operative relation with each other.

Fig. 5 is a detail perspective view of a portion of an operating key for the composite quoin shown in Fig. 4:.

Figs. 6 and .7 are perspective views of auxiliary or register quoin sections.

In the exemplification of the invention, we have illustrated a portion or section of a chase, indicated at 10, which, for convenience, is provided with a form, shown composed of a number of cuts or electro-plates 11 which have been properly inserted in the chase section and held in position by means of the usual furniture shown at 12. The different pieces of the furniture are shown locked in place by quoins 13, which may be of a well known construction, comprising two wedge-shaped sections adapted to move endwise in opposite directions so that the enlarged or base portions of the two sections will be moved toward each other. The quoins shown at 13- will, however, not permit or provide the nice adjustment frequently necessary with cuts or electro-plates for the purpose of securing proper alinement. I

To enable such accurate and fine adjustment, we provide the locking means hereinafter described and comprising the quoin illustrated. in Fig. 4, which consists of the female quoin section 14: shown in Fig. 2, and provided with a groove or channel '15 disposed lengthwise and throughout the entire length of the quoin section at the longitudinal center line thereof. The section 14 is thus provided with two side walls which are provided with the sloping or curved surfaces 16, 16. In order to give a greater range of adjustment, the side walls are preferably provided with a slightly greater slant or slope at one end of the quoin section, as for example shown at 17 in Fig. 2; the crown of the curved. or oppositely slanting surface being preferably at the transverse center of the quoin section, namely at a point preferably in alinement with the keyreceiving opening 18 which is formed in the female quoin section 14 and disposed transversely thereof from side to side, as shown in 2, thus permitting the key to be inserted from either side. The key-receiving opening is, partially formed in the base of the quoin section in order to permit the insertion of the key, a portion whereof is shown at 19 in Fig. 5, when the two quoin sections are in juxtaposed or operative relation with each other.

Fig. 3 illustrates the other or male quoin section 20, consisting of a main wedgeshape body provided, along the longitudinal center line thereof, with a toothed rib or rack portion 21 which is adapted to extend into the channel or groove 15 of the female section 14. When the rib 21 is in serted in the channel 15, the side portions or walls of the female section 14 will bear on the male section on opposite sides of the rib or rack portion 21; the channel 15, however, being; preferably of greater depth than the height of the rib or rack port-ion so as not to permit the rack portion 21 of the male member to come into absolute or bearing contact with the base portion of the female member. The key-receiving opening 18 is so formed transversely of the section 14 that its center will lie beyond the horizontal plane of the tips of the teeth of the rack portion 21 in order to permit the ready insertion of the key, as clearly disclosed in Fig. 4.

The female section 14. on opposite sides of the key-receiving; opening),- 18, is also provided with small pin-receiving; openings 22 22 adapted to extend through both sides in registeringrelation, so as to permit the insertion of a small pin .13, see Fig. 4, which is adapted to extend from side to side of the quoin intermediate of the tips of two adjacent teeth of the rack portion 21. The inserted pin 23 will not only prevent any longitudinal movement of the quoin sections relative to each other, but also enables the locking of the quoin on what is known as the half point system; as the two openings 22, 22 are spaced apart a distance and so related to the width and spacing of the teeth of rack-portion 21 that one of the holes 22 will always register with a space intervening adjacent teeth and thus permit the half point longitudinal adjustment of the quoin sections relative to each other.

The quoin sections are inser ed intermediate of the furniture and the form of type or cuts as shown in 1; and by reason of the construction of the female quoin section, it is apparent that a considerable latitude or range of adjustment may be obtained by the apposition of the base end of male quoin section 20 to either end of the female quoin section 14. It is also apparent from the construction that our improved quoin is especially adapted to situations where it becomes necessary to tip a portion of the form or cut, as for example shown at the lower right hand corner of the chase in Fig. 1, in order to secure a proper register. The rocker relation between the two quoin sections enables the quoin to adjust itself to any angularity, as shown at 24 in Fig. 1; while the outer surfaces of the quoin sections will constantly remain in firm and square contact with the form or cut and the furniture or adjacent cut.

The sides of the quoin sections 14 and 20 are both scored or lined, as shown at 25, 25, arranged at equal and similar distances apart on both sections, to assist the operator in determining the previous wedging; relation of the sections in the rearrangement or readjustment of a portion of the form and thus enable him to readily obtain the proper locking relation.

In situations where the margin or space intervening different portions of the form or cuts is such that the quoin represented in Fig. 4 cannot be employed, we provide the type of auxiliary members shown in Figs. 6 and 7 which may be employed as a complementary quoin adapted for use, as shown in Fig. 1, where the auxiliary members are shown in the narrow spaces between the cuts and the furniture and in opposing relation with the main quoin heretofore described and illustrated in assembled relation in Fig. 4.

The auxiliary members comprise a right angular wedge-shape section 26 having a flat outer surface, with an inner inclining surface provided with transversely disposed grooves, preferably extending the full width of the section, so as to provide a plurality of teeth 27, as shown in Fig. 7. The other section or member 28 of the auxiliary quoin, illustrated in 6. is provided with an outer flat surface and an inner surface havinp; a transversely disposed ridge or rib 29 preferably extending; from side to side and at a point centrally between the ends of the section. The inner surface of the section or member 28 is sloped or tapered in opposite directions from the central ridge or rib downward toward the ends of the sections, so that the section 28, when brought into operative relation'with section 26, will permit the rib or ridge 29 to lie intermediate of adjacent teeth 27 and allow the section or member 28 to rock or tilt on the ridge or rib; in other words the section or member 28 is of greater thickness, preferably at a point centrally between the ends of the member, with the oppositely disposed taper of the inner surface such that the apeX 0r crown of the inner surface is adapted to fit in between adjacent teeth of the other section or member 26 and thereby maintain the adjusted relation between the members.

As an illustration of the manner in which this auxiliary or complementary quoin may be employed, we have shown the same at 30 in Fig. 1 arranged in opposing relation with the other or main quoin shown at 24, namely in places where the space between portions of the form is too small or narrow to permit the use of the large quoin shown at 24:.

The auxiliary quoin 30, like the quoin 24, will adapt itself to any angularity of the form or cuts, because of the rocking or tipping relation between the respective sections; while at the same time the outer faces thereof will provide a firm and comparatively large bearing surface on the cuts and furniture or adj acently placed cuts or portions of the form.

Our improved quoins greatly simplify the movement or adjustment of individual portions, especially in large forms consisting of many parts, without disturbing the permanent lock-up of the form in general as has heretofore been necessary in order to move any part of the form which was not in proper register. It is also evident that our improved quoins will find their own level, so to speak, and thus save considerable time heretofore spent in what is termed as work up caused by the springing of the form; as the rocking or tilting relation between the quoin sections enable the respective sections to adjust themselves to the angles developed in the assembly of the form, especially where multi-colored printing is being done; the quoin sections, however, at all times firmly holding the parts of the form in proper position after the form has been locked up.

We have shoWn and described what we believe to be the simplest and best forms of our invention; modifications, however, may be made in certain details without, however, departing from the spirit of our invention.

What we claim is 1. In means of the class described, a pair of quoin sections, one section being provided with a channel disposed throughout the length thereof and with two side walls both of which are formed with oppositely sloping bearing surfaces, the slope of said surfaces being such that the opposite ends of each side wall will be disposed in a different horizontal plane, while the other section is of right angular wedge-shape and has a toothed rib or rack disposed throughout the length of said section, intermediate of its sides, adapted to extend into the channel of the first mentioned sectionn said second mentioned section being provided with flat bearing surfaces on opposite sides of said rib or rack adapted to bear on the bearing surfaces of' the first mentioned section, the fifst mentioned section being provided with transversely disposed key-receiving openings and with transversely disposed locking pinreceiving apertures arranged in communication with said channel, said aper tures being arranged on opposite sides of the key-receiving opening, the apertures and teeth of the toothed rib or rack being correlated so that one of said apertures will always register with the space intermediate of the teeth of said rib or rack.
